The ramp from the Easton-Phillipsburg toll bridge will be inaccessible 6 a.m. Monday until 4 p.m. Thursday, the commission said in a news release. It could be longer depending on weather, traffic and emergencies.

The bridge rehabilitation includes curb and storm sewer work and replacing guide rails, the commission said.

Drivers should go slower and use caution in active work zones, the commission warns.
